Insulin is produced by beta cells of the pancreas for storing and disposing of the glucose in various parts of the body like liver. This activity is a differentiated function of the beta cells of pancreas only. Although gene for insulin production is present in all cells, it is expressed only in the beta cells. Hence, it is a differentiated function.

Question continuation;
..........type B. Type A is found to be more common in the mainland population from which the island was settled.
How could a geneticist best explain the dominance of blood type B in the island population?
Multiple choices;
A. Random mutations have occurred in the island population.
B. Genetic drift has reduced the frequency of type A individuals.
C. Natural selection has only occurred in the mainland population.
D. Environmental conditions on the island are less favorable for type B individuals.
Answer;
B. Genetic drift has reduced the frequency of type A individuals.
Explanation;
-Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance.
-It occurs in all populations of non-infinite size, but its effects are strongest in small populations.
If you want water to flow out of the tubing piece filled with a 50% solution, the minimum concentration of the solution in the beaker must be more than 50%. This is because, water can only flow out of the tubing piece if the concentration of the water inside the beaker is greater than that of the tubing piece; the water will move from the region of low concentration to the region of high concentration.
